Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a device for fixing a window glass to a window frame of an automobile body, and the invention relates to a device for fixing a window glass to a window frame of an automobile body. a glazing frame having a glazing frame, a corresponding form-locking joint arranged on the flange of the glazing frame extending parallel to the glazing pane, and a soft elastic molded packing acting between the glazing pane and the flange of the window frame; If the window pane with the glass frame is then moved at its form-locking part in a direction perpendicular to the window pane surface and to the plane of the window frame flange,
It relates to a type that can be locked with a shaped portion corresponding to On. It is obvious that in this case the glass frame may completely surround the automobile window glass or may consist of several parts. The glass frame may be fixedly connected to the motor vehicle window in any desired manner. In particular, the glass frame may already be permanently attached to its edge during the manufacture of the motor vehicle window. In any case, when lowering the automobile window glass or when lowering the vehicle body and the window frame, it is important that harmful tolerances do not interfere with the fitting of the automobile window glass into the window frame. In a known embodiment of this type (DE-OS 33 33 672), the production of the left section constituting the glass frame is optional. The form-locking connection is not provided in the glass frame. These form-fitting connections consist of split clips arranged at intervals along the sides of the glass frame, which split clips are ultrasonically welded to the glass frame sections. The corresponding form-locking element in this case is a hole provided in the window frame flange, into which a split clip is introduced when the window glass is inserted. The split clip must then be secured by the split bin. The split pin can be removed when disassembling the automobile window glass. Particularly when manufacturing automobile windows, when fitting the frame to the window and welding the split clips thereto, due to tolerance reasons, the split clips must be inserted into the holes provided in the window frame flanges at the automobile factory. It cannot be ruled out that they do not fit together or do not fit together accurately enough. To that extent, troublesome fitting problems arise with the known embodiments. The molded packing is placed behind the glass frame towards the inside of the window opening. Therefore,
To seal the gaps that occur there, additional packing in the form of special parts is required between the glass frame and the vehicle body. The known embodiments are therefore not suitable for carrying out automatic mass production due to the large number of parts and manufacturing techniques as well as due to fitting problems (for example German Patent Application No. 3,604,309). Problem to be Solved by the Invention It is therefore an object of the invention to provide a device of the type mentioned at the outset, which can be easily installed and worked with extremely simple parts, and which can also be used for automobile window glass. No more troublesome fit when fitting into the window frame!・No problems occur,
Another object of the present invention was to improve the ability to compensate for tolerances regarding automobile window glasses and window frame flanges of automobile bodies.

Means for solving the problems
L
A corresponding form-fitting connection is molded on the shaped strip, the other 17-shaped flange of said strip being fitted with its U-shaped receptacle to the edge of the window frame flange, forming a form-locking connection as well as a corresponding form-fitting connection. can be mated to compensate for tolerances, and
and that the molded packing is connected to the molded web of the glass frame towards the glass edge of the pane.

Operation and Effects of the Invention The invention forms a longitudinally extending form-fitting joint in the profile without the need for special working steps (which are necessary for welding the split clips of the known embodiments). Take advantage of the fact that you can. This applies in particular to profiles produced by injection molding methods, which are installed in motor vehicle glazings. Providing a corresponding form-locking connection greatly simplifies the manufacture of the component.

This provides the parts and molded form-lockings with an extremely high degree of precision, which is a prerequisite if precisely molded parts are to be joined to motor vehicle window frames or window frame flanges. It is possible to compensate for tolerances resulting from the fact that motor vehicle window panes as well as motor vehicle bodies or their window frame flanges have slight inaccuracies, since the form-locking joint and the corresponding form-locking joint are designed to compensate for the tolerances. This is because they can be combined in a compensating manner. This can be accomplished in a variety of ways. One possibility consists in configuring the parts to be sufficiently deformable.

Another possibility consists in providing several form-locking connections, for example locking steps.

A second degree of freedom for the desired tolerance compensation results from the fact that the seven-shaped strip can be pushed with its U-shaped receptacle into the window frame flange with different widths. Therefore, the aforementioned fitting problems are largely eliminated. Of course, the components of the device according to the invention should be constructed in such a way that any loads occurring during operation of the motor vehicle can be absorbed and that they can be securely connected during installation by a simple snap-lock. . Nevertheless, with the device according to the invention it is possible, if necessary, to dismantle the motor vehicle window and the glass frame attached to it in a simple manner. For disassembly, it is sufficient to bend the form-locking joint and the corresponding form-locking joint in opposite directions; this operation can be carried out by compressing the molded packing, ensuring that the locking joint is always sufficiently elastic. This is possible because it is deformable. In this case, a thin plate piece or similar member that holds the form-fitting part and the corresponding form-fitting part in the expanded state should be inserted into the locking joint part which has been expanded using a suitable tool in the direction of the glass frame. I can do it.

In particular, there are numerous possibilities of alternative configurations and shapes within the scope of the invention. In this case, the glass frame consists of a generally double-shaped profile in cross section, which profile is connected to the motor vehicle window glass by its double-shaped web and one double-shaped leg, and the other It is common for the legs of the 2-shape to have a form-fitting joint. Profiles with just this cross section can be manufactured simply and with great precision using the strand pressing method. In this case, the Z-shaped leg connected to the motor vehicle window can be provided with a U-shaped receptacle, which is attached to the glass edge and thus at the same time ensures a correct installation of the glass frame part. In a preferred embodiment of the invention, the two-shaped leg provided with a positive connection has a U-shaped recess, which is provided with a positive connection on the inside. In this case, the 5-shaped strip is provided with a form-locking connection which fits into the U-shaped recess. The form-locking connection and the corresponding form-locking connection are advantageously designed as serrations. For reasons of mounting technology, the molded packing should be permanently bonded to the glass frame. This bonding can in principle take place by coextrusion. However, it can also be done by gluing. In any case, the glass frame should already be equipped with a molded seal when fitting the motor vehicle window. Of course, the molded packing is transferred to the molded web only where the glass frame is present. Only if the glass frame consists of spaced-apart frame parts can the molded packing itself be fixed to the motor vehicle window in this area. The molded packing is connected to the molded web of the glass frame towards the outer edge of the vehicle glazing, so that the molded packing is connected to the molded web of the glass frame, if necessary, between the vehicle glazing edge where the glass frame is fitted and the vehicle body. It can have a shaped flange bridging the gap. Of course, the body flange or the five-shaped strip can be provided with roughenings and moldings to prevent slippage. The flexible frame part may be fixedly connected to the rigid part or to the pane to prevent slipping. In any case, an all-encompassing seal should be ensured. Within the scope of the invention, it is also possible to configure the figure-7 strip to be movable on the window frame flange, but to be able to be fixed by the pressing force of a soft elastic molded packing when the glass frame is locked. can.

The components of the device according to the invention can be manufactured from various feedstuffs. In particular, the glass frame as well as the figure 5 strip,
There is also the possibility of molding from hard elastic plastic, possibly with embedded reinforcement. The molded packing can also be constructed as a soft elastic plusdeck member. The soft glass frame part may also be constructed in a soft manner with a hollow chamber. A particular advantage is that the components of the device according to the invention can be manufactured easily and within the scope of large-scale production.

Particularly within the scope of the two-stage injection molding method, it is possible to apply the window frame to the automatic double glazing by injection molding, or to produce a molded packing and combine it with the glass frame. In this case, it is possible to work with various materials. A prefabricated part of the device according to the invention, for example a form-fitting part, can be inserted into the injection mold. Of course, the components of the assembly according to the invention can also be produced in a strand press method and applied to a motor vehicle window.
